ATHENS, Greece – Archaeologists armed with top-notch technology have scoured one of the richest shipwrecks of antiquity for overlooked treasures, recovering a scattering of artefacts amid indications that significant artworks may await discovery under the seabed.

The Roman wreck off Antikythera Island, southern Greece, was located more than a century ago, when divers in primitive suits raised marble and bronze statues, luxury tableware and a complex clockwork computer.

Over the past three weeks, a U.S.-Greek team comprehensively mapped the seabed, and divers raised a bronze spear that probably belonged to a larger than life-sized statue, and metal fittings from the 1st century B.C. wooden ship.

A Greek Culture Ministry statement Thursday said divers with metal detectors also located "strong signals," which could point to ancient artefacts that evaded the first investigation in 1901.
